PHOTOGRAPHIC-FILM HOLDER.

Application filed July 19,1922. Serial No. 575,944.

To all whom it may concern:

Be it known that I, HARRY C. STRIEKER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Photographic-Film Holders, of which the fol lowing is a full, clear, and exact descrip tion, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a light, cheap and effective device for holding the long strips of photographic films for developing, washing, drying and otherwise handling, particularly in the case of films which have been mounted in rolls, and which unless held taut and properly stretched, tend to curl up during the developing and sub- 2 sequent operations.

My particular object is to provide a holder in which the frame and mounting posts shall be formed from integral strips of wire properly bent and interlocked, so as to furnish an exceedingly light and durable construction without any liability of becoming warped in use and without danger of the posts or other parts becoming loose 0r disconnected, and which can be manipulated in a single operation to stretch or release the film from the holder.

These features and others to be noted will be fully set forth and described in the specification and claims that follow.

In the drawings, which illustrate my preferred form of construction,

Figure 1 is a perspective view of the holder without the film.

Figure 2 is a similar view with the film mounted on the holder.

The holder comprises an open framework of the desired length and width for the size of the film to be mounted thereon, which frame is formed from a single strip of wire 1 bent to form a rectangular frame.

The wire is given a right-angled bend at each of the four corners 2, 3, 4 and 5 and the frame is closed by bending and interlocking the wire at 7 and 8, and two upright posts 9 and 10 are formed by extending vertically upward the end portions of the wire.

Mounted to slide on this frame is a slide formed of two pieces of wire twisted together at 12 and bent to form loops 13 and 14 to engage around the sides of the frame.

The ends of these strips of wire are bent vertically upward, the ends of one to form outside posts 15 and 16, and the ends of the other to form inside posts 17 and 18; these posts together with the posts 9 and 10 of the frame strip are preferably of a height slightly greater than the width of the film to be mounted thereon.

When it is desired to use the holder, the slide piece is moved towards the end posts, and one end of the film 2O slipped over one of the inner posts, as 18 of the slide piece. To make a loop for the end of the film to en gage the post, the ends of the film may be folded over and pinned. With the sensitive side of the film outward, the web is passed around post 10 of the frame, carried around the outside posts 16 and 15 of the slide, thence around the other frame post 9 and back to the inner post 17 of the slide, where the other end of the film is formed into a loop to slip over the post. The operator then draws back the slide and the desired tautness of the film is obtained. 1

By reason of the fact that the loops of the slide piece are of wire and have frictional engagement with the sides of the frame, the slide will hold its position wherever placed, and thus the film will be held taut during the finishing operations.

When thus made of wire, the posts cannot warp or become loose and disconnected. The holder is light and the slide can be instantly manipulated to tighten or loosen the film, while the end of the frame beyond the film becomes a convenient handle for the holder and avoids the liability of contact with the sensitized surface of the film when mounted on the holder.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A photographic film holder comprising an open wire frame formed from wire with the end portions interlocked to form one end 1 of the frame, and with the ends projecting upward to form posts, and a slide piece mounted on the frame to slide lengthwise 1 thereof and provided with upright posts to co-operate with the frame posts for holding a web of film.

2. A photographic film holder comprising an open wire frame formed from wire with the end portions interlocked to form one end of the imle and With the ends projecting upward to form posts, one at each of two of the end portions interlocked to form one end 10 the corners, and a slide piece mounted on of the frame, and with the ends projecting the frame to slide lengthwise thereof and upward to form posts, and a slide piece comprovided with upright posts, one pair oppoprising wires twisted together and looped 5 site the frame posts and the other pair 011 around the sides of the frame with their the inside, to (Jo-operate with the frame posts ends projecting upwards to form posts to 15 for holding i Web f co-operate with the frame posts.
